To all lLaiton?, t may conce/m.'

lie it lrnown that l, Willman Ginori, a subject of the lling or'England, and a resident ci fpringiield, in the county ci Hampden andtltate oie Massachusetts, have inventeda useful Burner, ci which the sspecilication. illy invention relates to improvements in devices orappiicancesi'cr burning gas tor heating purposes, and residesparticularly in a hollow, slotted, burner head, to Which are and airinlets, and a hollow, slotted mixer or breaker supported in said head,both oi peculiar construction and combined in a novel manner, togetherwith such other parte and .members as may be necessary or desirable inorder to render the device complete and serviceable in every respect,all as hereinafter set forth.

ihe primary object ci' my invention is to produce a gas burner in whichthe gas and air are so thoroughly and completely broken up and mixed,before arriving at the place o combustion, that an intense blue tlame isproduced such place, and suoli flame is normally projected aconsiderable distance from the burner, or is caused to spread over alarge area when directed against a plate, crown-sheet, water-leg, orother resisting member located more or less closely to the burner,wherefore the latter is especially well adapted to use in steam-boilersand other heating apparatuses for houses and buildings.

Another object is to produce a burner of this character which iscomparatively simple and inexpensive, yet strong and durable, consistsof ew parts which are not liable to become disarranged or get out oforder, and withal is highly eiicient and entirely prac ticable.

iVith this burner, due to the intensity and volume ot the dame producedthereby, a great economy in the consumption of the gas ifor heatingpurposes is eii'ected, and this is an exceedingly valuable feature ofthe invention.

The burner having the straight burner head can be used with practicallyequally goed results in either a vertical orhorizontal position, and thesame may he true in some cases in regard to the burner having an annularburner head.

Other objects advantages will appear in the course ot the followingdescription.

l attain the objects and secure the advantages ci my invention by themeans illustrated in the accompanying drawings, in Which+ Figure l is aside elevation of a gas burner which embodies a practical form of myinvention; Fig. 2, a central, vertical section through said burner; ldig. 3, a top plan of the burner; Fig. 4, a central, vertical sectionthrough the upper part of the burner, taken at right-angles to thesection in F ig. 2,' Fig. 5, a developed plan of the mixer or breaker;Fig. (l, a bottom plan of the burner; ig. 7, a top plan ci a inoditledform or' the burner; lig. 8, a central, vertical section through saidmodification, with parts broken away to economize space, and, Fig. 9, adevelo ed plan of a breaker wherein there is a slight change in thelength and arrangement of the slots therein.

Similar reference characters designate similar parts throughout theseveral views.

ln the embodiment of my invention, as illustrated in the iirst sixviews, the gas burner comprises a hollow member or tube l having aflaring base 2 and a slotted crosshead which forms what I term a burnerhead 3, a gas-inlet nipple i supported in said base by a cross-piece 5,a hollow, cylindrical, slotted mixer or breaker 6, and means to supportthe latter in said burner head, such means in the present exampleconsisting of a pair of specially constructed screw-plugs 7. 7Ifhe tubel, base 2, burner head 3, and cross-piece may all be integral.

The nipple Il is tapped into the center of the cross-piece 5, with theaxis of said nipple coinciding with the axis of the tube l. The nipple 4is internally screw-threaded at the outer end for the attachment theretoof a tube or pipe which leads from the gas supply, and there are three,more or less, perforations 8 in the inner end of said nipple around aconical projection 9 that extends inwardly from the center ci said end.A cap l0 is provided for the inner end of the nipple Ll, and is inscrew-threaded engagement therewith. ln they center of the cap 10 is anopening l1 into which the projection 9 extends. Gas entering the nipplell, from the supply tube or pipe, passes through said nipple and theopenings 8 into the cap 10, and out around the projection 9 through theopening 11 into the tube l. rihe projection 9 serves as a needle-valveby means of which "nfl and the cap 10 the amount of gas permitted toescape into the tube l is regulated. This means of controlling the ow ofgas is old and well known, and any other suitable means might be'substituted thereforo Air enters the tube l through the flaring base 2around the nipple et and the cap 10 and on opposite sides of thecross-piece 5. The air and gas commingle in the tube l and pass throughsaid tube into the interior of the burner head 3.

In the top of the burner head 3, when the device is positionedvertically, is a plurality of transverse slots 12. As shown in Fig. 4,the slots l2 are cut deeper on one side Athan on the other. The bottomsof the slots l2 on one side are approximately on the same horizontalplane with the axis of the burner head 3, while the bottoms of saidslots on the other vside are above such plane. It has been found thatcombustion is improved by cutting the slots deeper on one side than onthe other in the manner just explained. Combustion takes place as themixture escapes through the slots 12, on the outside of the parts of theburner head 3 which form said slots, or rather the slotted portion ofsaid head is enveloped by the flame which is projected therefrom aconsiderable distance, or caused to spread over a considerable area,provided the necessary structural conditions have been complied with andthe parts and members properly adjusted.

Extending longitudinally through the center of the burner head 3 is achamber into which the passage through the tube l opens, as clearlyshown in Figs. 2 and a, and such chamber continues'through the ends ofsaid head. This is the mixing chamber. The end portions of the head 3are internally screw-threaded to receive the screwplugs 7. i

Each screw-plug 7 is interiorly recessed to receive one terminal of thebreaker 6, and preferably the inne r-end portion of such plug is cutaway above and below, as represented at 13-13 in Fig. Ll. Oppositel 1-disposed, arcuate projections or lingers id--lllare left oneachscrew-plug 7 at the inner end after cutting away the parts at 13,which fingers receive between them and assist in supporting one terminalof the` breaker 6, without obstructing materially the adjacent slots insaid breaker, which slots are indicated by the numerals l5 and i521. Thelingers lll are screw-threaded cx-V te iorly, like the body portion ofthe screwplug 7, for engagement with the screwthreaded part at eitherend of the head `When properly positioned the screw-plug 7 is aranged sothat the fingers 14 are disposed crosswise of the head 3. In addition tothe lingers lli, the screw-plug has an annular recess therein for thereception of raedeee one extreme end portion of the breaker 6 in whichthere are no slots l5 or 15a. The support afforded by the aforesaidrecess might be sufficient without the fingers 14, onthe one hand, orthe fingers lll might be sufficient without said first-named support,von the other hand.

lnasmuch as the breaker 6 becomes hot, the screw-plugs 7 should bescrewed inwardly only so far as to a-ord the necessary support for saidbreaker and at the same time provide for the necessary expansionthereof. ln other words, there should be a loose lit between thebreaker' and each screw-plug. The ser; 2h' breaker with its axiscoinciding with the axis of the mixing chamber in the .burner head 3.

The slots l5 and l5 are laterally arranged, longitudinally of thebreaker 6, in staggered or offset relationship in said breaker. Theslots l5 are shorter than the slots 15, and all are arranged in rowscircuniferent'ially and longitudinally of the breaker 6, with anyintermediate slot 15a extending lengthwise in either direction betweentwo adjacent slots l5, and any intermediate slot l5 extending in eitherdirection between two adjacent slots 15. lt follows.y therefore, thatany two slots longitudinally are in staggered or offset relationship, oralternately arranged relatively. rlhe breaker slots may or may not allbe of the same length, and the distance which one slot extends in eachdirection lengthwise between the two slots on each side in each of thetwo adjacent rows, in a breaker of a given size may vary, as illustratedVery clearly in Figs. 5 and 9. In the Fig. 5 arrangement, the amount ofextension of a slot between the slots on each side in adjacent rows isgreater, and the distance between the ends of slots in the same rowcircumferentially is consequently less, than in the Fig. 9 arrangement,wherein the ends of the slots 15b in adjacent rows longitudinally of thebreaker are comparatively close together, and the distance between theends of the slots in the same row circiunferentially of said breaker isnecessarily and correspondingly greater. A breaker having therein slotsarranged as in Fig. y9 should be so placed in the burner head 3 that oneof the portions of said breaker in which are included adjacent andalternately-arranged end portions of the slots is uppermost in saidhead, rather than one of the portions wherein is included onlyl a singlerow of slots, in order to obtain the best results, because in the first.instance ythe maximum area of slots is present at both the. top andbottom of the breaker, and the passage through the latter of the mixtureand the delivery of the same at the place of combustion areenhanced orfacilitated. In

lll() dll ineens@ the other arrangement less care need be exercised inpositioning the breaker in the burner head.

ln practice, the gas and air which enter the base, inner end, or mouthof the tube 1, at 2, pass through said tube into the mi` chamber in theburner head 3, wherein the combined gas and air encounter the breaker 6and pass upwardly or outwardly around and through the slots 15 and 15ainto and out of said breaker, with the result that, by the time themixture arrives atthe slots 12 in said head, the constituent elements ofsaid mixture are so completely broken up and commingled as to burn whenignited at the place of combustion, with a iervency and force that arevery intense and quite superior for heating purposes.

The breaker 6 can be taken out upon removing either of the screw-plugs7, and a new breaker inserted in place of the old, should occasionrequire.

rllhe burner illustrated ink Figs. 7 and 8 consists of a tube 16 havinga flaring base 17 and provided with a cross-piece 18 in which is seateda nipple 19 that is provided with a cap 20, all similar to correspondingparts in the other burner, except that they are larger in the secondthan in the first burner. Mounted on orfintegral with the tube 16 is acupped member 21 upon which is an annular, slotted member22, the twotogether forming a circularl burner head with a mixing chamber therein.The members 21 and 22 are provided with exterior, coinciding, radiallugs 23 which are adapted to be secured together by means of screws 2l,said screws passing downwardly through the upper lugs 23 intoscrew-threaded engagement with the lower lugs 23. At 25 are representedlateral slots cut in the top of the member 22. The slots 25 are arrangedaround the entire circumference of the round burner head, being cut inthe member 22 in substantially the same manner as the slots 12 are cutin the burner head 3. 'lhe ends of each slot 25 may be on the samehorizontal plane, as shown in Fig. 8, or one end may be higher than theother, as in the iirst ein ample. The member 22 is cupped in the center,as shown at 26, to assist in forming a suitable receptacle for acircular breaker 27.

The breaker 27 is mounted in the round burner head in the annular spacebelow the slots 25, of which space mention has just been made, andbetween the part 26 and the outer or rim portions of the members 21 and22, the horizontal plane in which is located the annular center of saidbreaker being on a level with the plane wherein is located the junctionbetween said members. The breaker 26 has slots 15 therein, which slotscorrespond generally with the slots 15 and 15a, but might be like theslots 15".

Any suitable means may be provided for supporting the breaker 27 in thediametrical center ol the annular space provided for its reception, suchas three, more or less, lugs 28 rising from the member 21 beneath saidbreaker, and a corresponding number of crosspieees 29 above said lugs,said breaker being received on said lugs beneath said cross-pieces- Eachcross-piece 2d extends between the part 2G and the outer rim or themember 22, and has arcuate part to engage the breaker.

lt will bevnoted that the burner head slots are, in each case,considerably wider and larger generally than the breaker slots, but thatthe la 3 are more numerous. These relative diderenees are essential tothe success of the invention.

'lhe operation of the round burner is substantially the same as or verysimilar to that of the burner with the straight b ier head, only in thecase or the round burner annular llame produced.

More or less change in 'the shape, size, cons struction, et some or allof the arts of my gas burner, in addition to those hereinbelorespecilically pointed out, may be made without departing from the spiritor my invention, or exceeding the scope of what is claimed.
